Uninstall Regseeker completely from your system...and I mean completely....search it out with everything you have........when your satisfied that there isn't a speck of it left anywhere, reinstall it fresh from...

as no one has come up with anything i'll just say what i would do, but it's no more then an idea, sorry.

i think regseeker is finding something it doesn't understand and that stops it in its tracks. maybe if you use another cleaner first it may remove the problem value, also, doing what Cochise said - remove anything the other cleaner finds with regseeker in. then re-scan with a new copy of regseeker.

remember to backup the results of the other cleaner/s you use. i like JV16 and CCleaner together, they both have backup options.

another idea would be to put back the .reg file regseeker last removed, or whatever other cleaner you have cleaned with.
